✦ Synopsis

We study the interaction of dipolar excitons in a disordered lattice with a classically fluctuating bath to elucidate the effects of dephasing on phenomena connected with Anderson localization. We find general agreement with recent approximate analytical theory -the existence of incipient localization for dipolar excitons for a sufficiently disordered lattice and for states beyond a quasi-mobility edge. An interesting interplay with the band structure of dipolar excitons leads to some unusual results in the weakly disordered case.
